I've tested openSuSE 11.2 GNOME LiveCD Milestone 6 with my webcam Creative PC-CAM 600. gspca_main and gspca_sunplus modules are loaded, but the device video is not created. After unloading both modules and loading them, the device video /dev/video0 appears.
Can you provide the dmesg output from this machine after unloading and loading the modules?
With ekiga I've selected my webcam model, but I haven't seen any image. With cheese I've seen images from my webcam, starting the application with this sintax: LD_PRELOAD=/usr/lib/libv4l/v4l1compat.so cheese
What happens without the preload? Can you confirm that gstreamer-properties has the Video Plugin set to v4l2?
With skype the webcam video image is green, while with Adobe Flash Plugin the image is black
We can't fix those apps as they are closed source, sorry. -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

I have the same problem with my Creative WebCam Live! in 11.2 (x86_64), has anyone found a solution for gspca based webcams?
Please file a separate bug and assign it to me (bphilips@novell.com) and provide the output from hwinfo. Also ensure you have libv4l installed. -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

I've also compared the source sunplus.c included in openSuSE kernel with sunplus.c released by linuxtv.org. This version has an optimized code: http://linuxtv.org/hg/v4l-dvb/rev/7f60302cca90 and the brightness is signed: http://linuxtv.org/hg/v4l-dvb/rev/652a4093feba This patch is really useful because the video images from my webcam are too dark. Is it possible to include these improvements in openSuSE kernel? -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
